 I have a chart in my windows form which X-axis linked whit text box, containing names of elements and Y-axis linked whit text-boxes, containing numeric values.
when I debug the form columns (bars) are close together and from 5 columns just one column takes a name.
Also when the same names come in text-boxes the program gives the message " A chart element with the name "......." already exists in the SeriseCollection". how to solve this issue?


I have tried the following code:

What I have tried:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Try
            Me.Chart1.Series.Clear()
            Me.Chart1.Series.Add(Form3.TextBox6.Text)
            Me.Chart1.Series.Add(Form3.TextBox17.Text)
            Me.Chart1.Series.Add(Form3.TextBox23.Text)
            Me.Chart1.Series.Add(Form3.TextBox29.Text)
            Me.Chart1.Series.Add(Form3.TextBox35.Text)

            Me.Chart1.Series(Form3.TextBox6.Text).Points.AddXY(Form3.TextBox6.Text, Val(Form3.txtpi1.Text))
            Me.Chart1.Series(Form3.TextBox17.Text).Points.AddXY(Form3.TextBox17.Text, Val(Form3.txtpi2.Text))
            Me.Chart1.Series(Form3.TextBox23.Text).Points.AddXY(Form3.TextBox23.Text, Val(Form3.txtpi3.Text))
            Me.Chart1.Series(Form3.TextBox29.Text).Points.AddXY(Form3.TextBox29.Text, Val(Form3.txtpi4.Text))
            Me.Chart1.Series(Form3.TextBox35.Text).Points.AddXY(Form3.TextBox35.Text, Val(Form3.txtpi5.Text))

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        Finally
            Beep()
        End Try
    End Sub

VB

Me.Chart1.Series.Add(Form3.TextBox6.Text)
Me.Chart1.Series.Add(Form3.TextBox17.Text)
Me.Chart1.Series.Add(Form3.TextBox23.Text)
Me.Chart1.Series.Add(Form3.TextBox29.Text)
Me.Chart1.Series.Add(Form3.TextBox35.Text)

Suggestion: Use proper names for your textboxes that actually reflect the content of the box. Using the default VS generated names can lead to obscure bugs in future.
